Proton- A positively charged particle of matter which is found in the nucleus. It has 1,836 times the mass of an electron.
Neutron- Located in the nucleus. This part of the atom has no charge.
Nucleus- A positively charged mass in the middle of every atom, made of protons and neutrons. The nucleus on takes up a tiny part of the volume of the atom. **Click here for a picture of a nucleus.** //"How Lasers Work." Howstuffworks. Howstuffworks. 13 Dec 2006 http://www.howstuffworks.com
Electron Cloud- Electrons make up the electron cloud. The spaces in which energy exists are called orbitals.
Energy Levels- Different levels at which electrons exist.
What is Matter? Anything that contains mass and occupies space.
What is the Periodic Table? The table in which all known elements are listed and classified with Atomic Numbers and Atomic Weight.
What are the groups of the Periodic Table? The groups in the Periodic Table of Elements are called families. The families are Alkali Metals (Family 1) Alkali Earth Metal (Family 2) The Transitional Metals (Families 3 - 12) The Boron Group (Family 13) The Carbon Group (Family 14) The Nitrogen Group (Family 15) Chalcogens (Family 16) Halogens (Family 17) and Noble Gases (family 18).
What is the Periodic table? Who made it? When was it first Created? The periodic table is a table that was created to help show the families of different elements, and to show the amount of protons, electrons, and neutrons. The table itself however was created by Dimitri Mendeleev, a Russian chemist. It was first created in 1869.

Cinoman, Ryan. Personal interview. 12 Dec 2006.
1.) If Neon (Ne) has a atomic number of 10 and it's atomic mass is 20, then how many neutrons does Neon consist of?
2.) If Potassium (K) Has 19 protons and 20 neutrons what is it's atomic mass?
3.) What is the space in the electron cloud called in which the energy resides?
4.) How can you find out how many neutrons are in an atom?
5.) How do you find out the number of protons & electrons in an atom?
